The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s shaping up in our neck of the woods.
Overall, the next two weeks are a bit of a mixed bag with a lot of average, marginal days. The first week is pretty ordinary, with a lot of cross-onshore winds and small, weak swell keeping things messy. There’s a real standout period that starts to build late in the first week and carries right through the second week, with a couple of absolute gems for the crew who can wait.
The first decent run of waves kicks off on Thursday, 27 August morning. The swell is coming from the NE at 7 ft with a period of 8 seconds, and the combined energy is moderate (545). The real beauty here is the glassy conditions – that NNE wind at 3 mph is going to leave the surface clean as a whistle. Costeño Beach is a consistent spot, so it’ll be working. This is a solid option for intermediate surfers.
The best of the whole forecast, though, is Sunday, 30 August morning. We’ve got NE swell at 5 ft with an 8-second period, but the combined energy jumps to a strong 557. The wind is glassy from the ENE at 3 mph, making for perfect, clean conditions. This is the pick of the bunch for quality waves without the crowds being an issue.
Friday, 4 September morning is another real standout, but it’s a long way out. The forecast shows NE swell at 6 ft with a 9-second period and a combined energy of 542. Glassy conditions again with a 3 mph ENE wind. The afternoon session that day looks even bigger at 8 ft from the NE with an 8-second period and a combined energy of 708. That’s getting into the expert zone, but still glassy. Keep an eye on this one, but don’t book the trip just yet.
The water temperature is sitting at 83°F, which is pretty much spot on for this time of year, so the wetsuit can stay in the car.
The rest of the days are filled with cross-on breezes, small wind ripples, and average wave heights. There are a few glassy afternoons here and there, but nothing that’s going to get the heart racing until that late August/early September window.
Rusty.
